BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct Ilex plant, botanically known as Ilex×hybrida and hereinafter referred to by the name ‘EN1’.

The new Ilex plant is a product of a planned breeding program conducted by the Inventor in Poplarville, Miss. The objective of the breeding program was to develop new compact and uniform Ilex plants with mounding plant form.

The new Ilex plant originated from a cross-pollination during the spring of 2003 of an unidentified proprietary selection of Ilex×hybrida, not patented, as the female, or seed, parent with Ilex×hybrida ‘Conaf’, disclosed in U.S. Plant Pat. No. 9,487, as the male, or pollen, parent. The new Ilex plant was discovered and selected by the Inventor in 2005 as a single plant within the progeny of the stated cross-pollination in a controlled environment in Poplarville, Miss.

Asexual reproduction of the new Ilex plant by softwood cuttings in Poplarville, Miss. since 2006 has shown that the unique features of the new Ilex plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Ilex have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘EN1’. These characteristics in combination distinguish ‘EN 1’ as a new and distinct Ilex plant:

-   -   1. Compact, uniform and mounding plant habit.     -   2. Freely branching habit; dense and bushy growth habit.     -   3. Glossy medium green-colored leaves.     -   4. Good garden performance.

Plants of the new Ilex differ from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Ilex are more uniform and denser than         plants of the female parent selection.     -   2. Plants of the new Ilex have better leaf retention than plants         of the female parent selection.

Plants of the new Ilex differ from plants of the male parent, ‘Conaf’, in the following characteristics:

-   -   1. Plants of the new Ilex are more compact and mounding than         plants of ‘Conaf’.     -   2. Plants of the new Ilex have smaller leaves than plants of         ‘Conaf’.

Plants of the new Ilex can be compared to plants of Ilex×hybrida ‘EN2’, disclosed in U.S. Plant patent application Ser. No. 14/998,741. Plants of the new Ilex differ from plants of ‘EN2’, in the following characteristics:

-   -   1. Plants of the new Ilex are shorter than plants of ‘EN2’.     -   2. Plants of the new Ilex are less vigorous than plants of         ‘EN2’.     -   3. Plants of the new Ilex are less freely branching than plants         of ‘EN2’.

Plants of the new Ilex can be compared to the plants of Ilex×meservaea ‘Blue Princess’, not patented. In side-by-side comparisons conducted in Poplarville, Miss., plants of the new Ilex differed from plants of ‘Blue Princess’ in the following characteristics:

-   -   1. Plants of the new Ilex were more compact, mounding and         uniform than plants of ‘Blue Princess’.     -   2. Plants of the new Ilex had larger leaves than plants of ‘Blue         Princess’.     -   3. Plants of the new Ilex and ‘Blue Princess’ differed in fruit         color as plants of ‘Blue Princess’ had darker red-colored         fruits.

Plants of the new Ilex can be compared to the plants of Ilex×meservaea ‘Mesog’, disclosed in U.S. Plant Pat. No. 4,878. In side-by-side comparisons conducted in Poplarville, Miss., plants of the new Ilex differed from plants of ‘Mesog’ in the following characteristics:

-   -   1. Plants of the new Ilex had larger leaves than plants of         ‘Mesog’.     -   2. Plants of the new Ilex and ‘Mesog’ differed in fruit color as         plants of ‘Mesog’ had darker red-colored fruits.

Plants of the new Ilex can also be compared to the plants of Ilex×meserveae ‘Magland’, disclosed in U.S. Plant Pat. No. 4,878. In side-by-side comparisons conducted in Poplarville, Miss., plants of the new Ilex differed from plants of ‘Magland’ in the following characteristics:

-   -   1. Plants of the new Ilex were more mounding than and not as         upright and pyramidal as plants of ‘Magland’.     -   2. Plants of the new Ilex were smaller with shorter internodes         than plants of ‘Magland’.     -   3. Plants of the new Ilex had smaller and glossier leaves than         plants of ‘Magland’.     -   4. Plants of the new Ilex were more freely flowering and         fruiting than plants of ‘Magland’.     -   5. Plants of the new Ilex and ‘Magland’ differed in fruit color         as plants of ‘Magland’ had lighter red-colored fruits.
